Research Paper


We consider the subclass \(S(\beta ,\gamma )\) of the normalized analytic functions. The extended form of this class was introduced and investigated by Aghalary et al. (Tamkang J Math 39(4):325–334, 2008). In the present paper, we define two double integral operators which preserve properties of this class. Applications and consequences of the main results are also considered.
